A 29-year-old woman with a non-contributive history was referred to our clinic at 27th week of pregnancy because of a dilatation of the fetal lateral cerebral ventricles. During the scan we found a Dandy-Walker malformation with the abdominal mass representing liver hemangioendothelioma.

Images 1 and 2: 27 weeks of pregnancy; transverse scans of the fetal head show the dilated lateral ventricles, dilated cisterna magna, and the V-shaped cerebellum because of the defect of the inferior vermis.

Images 3 and 4: 27 weeks of pregnancy; transverse scans of the fetal head show the dilated lateral ventricles, dilated cisterna magna, and the V-shaped cerebellum because of the defect of the inferior vermis.

Images 5 and 6: 27 weeks of pregnancy; sagittal and transverse scans of the fetal abdomen show a septate mass representing the liver hemangioendothelioma.
